The MAES Environment
The following illustrates the MAES deployment environment:
MAES provides the environment for running components on a mainframe server. When a client establishes an APPC/VTAM session to MAES, the following events occur:
- MAES starts a new subtask running the CA Aion server component. This subtask is connected to a subtask descriptor (MST) chosen from the list of available descriptors.
- The client program loads the CA Aion interface DLL and issues function calls to the server component.
- As soon as the server component is initialized, it takes control of the APPC session, freeing MAES for other requests.
- When the server component terminates, it frees all its resources and returns control to MAES.
The following illustrates MAES request processing:
